inthe head 12 is mounted awindlass 18 which is provided with a Aremovable handle.

19. AV piston 19 is arranged within'the cyl-` inder 11 and'V is connected with the windlass 12. 0n the top and the bottom'of the piston p 20 are provided pump washers. 21 which are overlaid with metal `discs 22.' `A bolt 23 passes throughthe piston, discs' and washers which it clamps togethers The bolt' 23 is provided with -an eye 24 from which a cable 25 extends to the wiiidlassv 18. A compresf sion spring 26 is interposed between the head 12 and the top of the piston 20. A discharge pipe 27 leads from a point near the bottoni i of the cylinder 21 through thehead 12,. vL f part ofthe cyl- K y v ioo 11ovr This pipe is provided with a valve 28 and has extending from its end a iiexible tubing 29.

Vic

In Fig. 3, the piston 2O is carried' by a rod Y .suitably threaded. On the head l2a is rotatably mounted an interiorly threaded gear 31, the rotation of which causes longitudinal movement of therrod 30. A shaft 32 is rotatably` mounted in the head 12a and is provided' with a pinion 33 which meshes with the'pinion 31. yLAL-removable handle 34 is provided for rotating the shaft 82. 26 is interposed between the head l2a piston 20. Y

Inthe operation of thisfdevice, tliepiston and the 2O is'let down to the. bottom `of thefcylinder dispense grease from the cylinder, it is necg transmission diil'erential or the like essary only to open the valve 28, the spring 26 forcing the plunger 2O downwardly, thereby causing grease to ilow out through the tubing 29.5- After the cylinder has been practically emptied of grease, it may be refilled as above described. The thread on the rod' 30 is 'of such pitch that, under the influence of the spring 26,'it will cause the.

gear 31 torotate, thereby allowing downward movement oiE the plunger 20. Using this apparatus, the lubricant may be taken directly from the original container to the without any possibility of grit or the like getting into the lubricant. This device ensures that the Vlubricant is clean when lsupplied to the parts to be lubricated.

f Apertures 36 are provided at the top of the cylinderto permit return to the container oi' any grease that have worked plast the' plunger 20' and vto prevent any compression in the upper part of the cylinder. Pref- A spring remesas erably, a check valve 37 is provided in the pipe'27 so that the cylinder may be filled with lubricant upon lifting the piston 20, even though the valve 28 inadvertently be left open.

It is understood, of course, that various changes may be made in the structural details without in Yany way kdepart-ing from the spirit of the invention as set forth, in the appended claims.

I cla-iin:

l. A dispensing device for use with containers in which lubricant is marketed, said device Vcomprising a cylinder adapted fto be inserted through the aperture provided vin one end of such container, said cylinder having its lower end terminating in an obliquely arranged inlet flap valve, a head connected' tov said cylinder vto rest on the end' of Vsaid 70 container to` seal the same, a plunger slidably mounted in said cylinder, resilient means interposed between said plunger and said head, a delivery pipe leading from a point near the lower end oi said cylinder and passing through said head, a valve in said delivery pipe, andrmeans sealed' in said head for moving said plunger in a direction to compress said resilient means. 2. A dispensing device `'or use with containers in which lubricant is marketed, said device comprising a cylinder adapted to be inserted through the aperturer provided in one end ot such container, said cylinder having its lower end terminating in an obliquelyarranged inlet flap valve, al head' connectedV to said cylinder to rest on the end of said container to seal the saine, said head having va cavity communicating with said cylinder,

a drum sealed in said head and extending into saidv cavity, a Cable having one end connected to said drum and the other end to said plunger, resilient means interposed loe-V tween's'aid' plunger and head, a delivery pipe leading froina'point near Vthe lower Vend of said cylinder and passing through said head, and a valve'in said delivery pipe.
